'Patented Aug. 20, 1912.

Application filed February 9, 1912. serial No. 676,598.' l

To-aZZ whom t may concern Be it known that 1,' FRITZ L. ANDREmda citizenofthe United States, residing at .the city of Chicago, in .thecounty ofCook and State of Illinois; have V'invented .a new and 'use-fulfImprovement in Bed-Couches, Iot

which the following is a specification.

Myninventionrelates to articles of furniture in which anupholsteredjsofa may be.

changed from itsuse as suchinto a bed providedwith a suitable set .of'spr1ngs.' In

thesej-devices. the sofa seat `may be inverted and .the bed springs are'concealed 1n the body of the sofa under the seat with a'v space to holdthe mattress and bedding.

It is the object ofmy invention to providev a piece of furniture of thisclass in which the relatively movable parts are so balanced with.reference .to each other lthat they may be movedwwith slight Veffort tomake the changes, I[and also-to providean improved device ibywhich thetop and body portions4 of the sofal may be hinged togetherl and at.. thesa-me time be lgiven a smooth and uni-' form' .lateralmotion while beingunfolded.

The principles of trated in the drawings,` in which-- folded or Figure11 Irepresents a cross section `of my improved bed couch when open foruse as"v a bed; F1g..2 v1s a similar section showing thesame closed forusefas a` couch; Fig. 3 is a top view of Fig. I1.showingthe attachmentof the "bed springs; Fig. 4 is a vView similar .to Fig 2 .with/the toppartially opened; Fig'. .5 is .a v.detailj of hinge connection. I.

Further. `describingI my invention 4with reference to the drawings, in'{which like and 8. Rail 7 is supported inthe position shown in Fig. 1 bycranklevers 9 and 10 whichare pivoted at their upper ends to the railand at the lower ends to the sofa. body.

TheI crank lever 9 is extended downwardly fromthe lower pivot to form ashort arm 11 attached by means of a pivot 11 acting in 1 the slot' 11 tothe shift lever'12,rwhich in my invention are illus-` turn lispi-vcitedto the sofa body at'13; The end rail 8 is pivotally attached inAamanne'r similar to thatalready' described by means ofthe crank lever15 whiclrhas adownwardly projecting .arm 15, while the inner end .of therail 8 is connect-ed to the rail v7 '-bya bridge piece 25. AThevallinementfof,said

rails'a-nd the lbridge piece is eftected'by two members 26. and'29 eachpreferably provided with 'stops orianges 26 and 2 9 and pivoted togetherat3l. `The .member 29 is pivotally 2 54 and themember 26 is pivoted .at8 to 27. .When the'two members 26 and 29 are exthe upper .faces of 2 5and. 8`the-y .form 4a toggle joint which :holds therails7 and 8 .andgthe connecting ypiece25 inrigid 4alinement. .One end', of a connectingvrod 16is pivotall-y attached to 15 at `15 and the other end .is pivotedat 17 at the point at 'which the crank. leverlO-is attached to theattached at 30 to the end-of the bridge piece vtended so that the stops26 and 29 .rest on end rail 7. A coiled spring 20'has one end Y attachedat .the point 17 and the other end tos'the l.pivot bolt 13 of .the shift.lever 12.

Another :coiled spring 21 has one end attached 'to theend ofthe bedframe and the other to the s h'ft lever. The foregoing descriptionrepresents a device which is p'rovided in .duplicateat .each .end .ofthe couch and which said devices are connected 'by longitudinal barsv18-19` to each other,

which with the .end and body pieces form the frame work by .which aresupported the bed springs- 31. A longitudinal brace 31 should beextended centrally between the two end bridge pieces. 1

My improved device for hinging the parts togetherconsists of a pluralityof members 32 and-33 pivoted together midway of .their ends 34. One endof 33 is pivotally at tached to alink 35 which is rigidly secured to thetop member ofthe sofa, while the other end of said member 33fisvpivoted-to the `free or swinging end of a link 36, which:

is pivoted at 37 to the body portion of the sofa'. -In like mannermember 32I has one end pivoted to the link 38 rigidlyl attached' to thebody `of the sofa," while theother end' is pivoted to the .swinging link39 whichis in turn pivoted aty 40 t'o the top portion lof the sofa. The.construction is best shown in Fig. .4. Iffrom this position thetopfisturned outwardly Ato the position shown in Fig. 1 (and as enlar edinFig. 5), the members 32 and 33 will e extended turning on the pivot 34,'whereby the front' pieces of `the sofa will be extended andspaced fromv-each other. When the topis turnedV in the otherv direction 'as shownin;Ii`ig. 2 the, said members will be turned on the pivot so that 438will. be

the stationary bracket-s and y substantially alined with each otherinside the now closed body portion, permitting the ltwo finishing piecesto rest edge to edge with for by their outer faces 'flush `with 'eachother. This action of the two vmembers 'provided the attachmentofth'efr'ee'ends to the swinginglinks 36 and 39 by Ywhichthey are4permitted to-act in accordance-'with the movement ofthe swingingsofa'portion.

When the parts described are'inthe p osition shown in Figl1 and theouter 'o'rswing-y ing portion is lifted the tension'of spring 2 0 iacting through .the crank. lever() andthe with the free or swinginglever 12, whereby the slotted' end will be ,forcedagainst the actionfofspring 21 past lrigid stop.

connecting rodfl aids inthe initial portion of the'lift.' fTh'eapparatus on the .stationary portion -begii'is to revolve on the pivots9 under thetension of vthe spring and later under theinfluence ofgravity, until the swinging portion takes the position 'ap-i proximatelyshown in Figi/JE.v l-At this point the end railS will drop fromvits ownweight,

folding its'e f on the swinging portion', causing Fthe toggle joint,composedof members 30 26 and 29, to be broken, and allowing the bar 8 tofold over toward its final position in which it is spaced'from 7 bythebridge piece 25.- Meanwhile the pivot 17 will `contact thedeadcenter, permittin the crank lever 9 to swing downwardly into 'theposition shown in Fig. 2,' at which pointl the engage-v ment ofpivot-11. in the 'slot y11 acts as a It will be noted that the said slot-provides means by. which thecircular i aidedV by the tension A21-,while the final movement is retarded, by

` .the ylower arm 1574s checked by its attach` movement of crank lever 9vis'ee'ct'ed, while retaining `engagement with the shift '.le-

In the initial reverse movement Of' thparts from pbsition in Fig. 2 theaction is of both springs 2 0 and the action of said springs. 4At thesame time the complete extension of-bar .8 is made as ment throughconnecting rod 16 with crank fportion movable the combinat-'on on thetop part, albed sectionfon'thev body t ing'a crank-lever having-a longand a short l and having a the short arm of'said crank-levenand means'lever V10.
